Innovative seismic design of bridges of the South Carolina Department of Transportation (SCDOT)

<em>Abstract</em>.—In support of the Magnuson–Stevens Conservation and Management Reauthorization Act of 2006, which tasked regional fisheries management councils with ending overfishing of numerous marine finfish species, the South Atlantic Fisheries Management Council established 8 deepwater (90–150 m [300–500 ft]) type II marine protected areas (MPAs) along the coastline of the southeastern United States. At the request of the South Carolina Department of Natural Resources (SCDNR), one of these MPAs was established on an undeveloped sand-bottom area previously permitted by SCDNR for artificial reef development. After monitoring the production potential of unfished artificial reefs for several years on shallower experimental reef sites, SCDNR staff proposed that a deeper location had the potential to become a highly productive spawning site, particularly for deepwater grouper species. Development of this permitted site began in 2014 when two 79-m (260 ft) barges with nearly 30 m (100 ft) of added profile were deployed. Subsequent monitoring of the site through remotely operated underwater vehicle video revealed colonization by several target species, including Warsaw Grouper <em>Hyporthodus nigritus</em>, Snowy Grouper <em>H. niveatus</em>, and Misty Grouper <em>H. mystacinus</em>. Due in part to the success of this deepwater MPA, the SCDNR was also granted spawning special management zone designation for its two previously established, undisclosed experimental artificial reef sites in federal waters off South Carolina in 2017.

Groundwater levels are examined to document and evaluate short- and long-term trends observed in each of the major aquifers in the State. Data are compiled from groundwater-monitoring networks maintained by the South Carolina Department of Natural Resources (DNR), the South Carolina Department of Health and Environmental Control (DHEC), and the United States Geological Survey (USGS). The data are used in the support of groundwater management and allocation, assessment of droughts, groundwater-flow modeling, and resource assessment. Hydrographs from approximately 170 wells are reviewed with periods of record ranging from 1 to 56 years.

Over the past several years, traffic fatality rates in South Carolina have been consistently ranked among the highest in the country. Furthermore, South Carolina incurs an annual economic loss of over two billion dollars because of roadway traffic crashes. The South Carolina Department of Transportation, in collaboration with the South Carolina Department of Public Safety, has undertaken a series of initiatives to reduce the number of vehicle crashes, with a particular emphasis on injury and fatal crashes. One of these initiatives is the deployment of a map-based geocoded crash reporting system that has greatly improved the quality of crash location data. This paper provides an assessment of improvements in crash geocoding accuracy in South Carolina and how improved accuracy is beneficial to systematic statewide safety analysis. A case study approach is used to demonstrate practical applications and analysis techniques based on spatially accurate crash data. A survey of U.S. state highway agencies indicates that there are disparate crash reporting systems used across the country with regard to crash geocoding procedures and accuracies. Survey results indicate that not only does geocoded accuracy of crash locations vary by state, but accuracies often vary by jurisdiction within each state. Research results suggest that poorly geocoded crash data can bias certain types of safety analysis procedures and that many state safety initiatives, analysis methods, and outcomes can benefit from improving crash report geocoding procedures and accuracies.
